## Questions & Answers

**Q: What is the method of how to open them? Do you need to have a separate tool for that?**
A: The best way to open them is to take a large file & carefully cut a groove around the Geode along any depressions in the shape. Place in on a towel on a concrete floor. Be sure to put on safety glasses! Take a large chisel and place it in the groove. Strike the end of the chisel with a hammer to break the Geode open. Be careful everyone standing near has their safety gasses on as well!

**Q: Can use  a sharp,big knife or if not, what do you use**
A: Please do not even consider attempting this with a knife.  That is an E.R. trip in the making.  We were quite successful with a hammer and wide chisel.

**Q: Does the item include a hammer?**
A: If you don't already have a hammer, this item is not for you.

**Q: Are they fake**
A: They are real just not real impressive. You're better off to buy bigger geodes online. The kit has nothing spectacular you need. My package was full of solid rocks. Took a 5 lb sledge to get the apart. 100% waste of money.
